Apple releases second developer beta of macOS Catalina 10.15.1

Apple is now on its second try for the macOS Catalina 10.15.1 beta, with developers able to download the second build of the operating system update to their Mac or MacBook for testing.




The new build of the operating system can be downloaded from the Apple Developer Center by those taking part in the testing program, along with the option to perform an over-the-air software update for devices already enrolled into the scheme. A public beta is typically made available shortly after the developer version is distributed, via the Apple Beta Software Program website.

The second beta of macOS 10.15.1 follows six days after the first build was issued for testing, and one day after counterpart betas for iOS 13.2, iPadOS 13.2, tvOS 13.2, and watchOS 6.1.

Though it is an incremental update, with major changes unlikely to be made so soon after Catalina's launch, there are still smaller changes being made to the operating system. The key change this time around is support has been added for the AMD Navi RDNA architecture, increasing the range of graphics cards that can be used in eGPU enclosures.

Other changes 10.15.1 include new emoji mirroring the new additions made in iOS and iPadOS, and a screen asking if users will allow Apple to review audio of Siri queries to improve the digital assistant.

AppleInsider, and Apple itself, strongly recommend users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
